## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tollex-x402-facilitator-status-check-14c3e488 -d '<json body>'
```

Example prompt: Before my agent tries to pay the merchant at https://merchant.example/v1/quote, check its x402 facilitator status to confirm it's active and ready to accept USDC payments.

## When to prefer this

Use this endpoint when an AI agent or orchestration system needs to verify that a specific x402-compatible merchant URL is live and accepting USDC payments before committing to a transaction. Prefer this over generic HTTP health checks when x402 protocol compliance and payment readiness (not just HTTP reachability) must be confirmed. Especially useful as a pre-flight step before autonomous agent payments to avoid wasted gas or failed transactions.

## Known failure modes

- Invalid or malformed URL returns a validation error
- Merchant endpoint is unreachable or offline — returns inactive/error status
- URL does not implement x402 protocol — returns unsupported or unknown status
- Network timeout if merchant server is slow to respond
- URL scheme not http/https — rejected by input schema pattern validation

## How this service works

Tollex lets software agents buy APIs and tools under rules you set: it finds a capability that fits, checks your policy before anything is signed, pays with x402 in USDC on Base or USDG on Robinhood Chain, reconciles uncertain payments and returns a signed receipt.

## Output

Returns the current facilitator status of the given merchant URL, indicating whether it is active, reachable, and capable of processing x402 USDC payments on Base or USDG on Robinhood Chain. May include signed receipt or payment reconciliation metadata.
